A na-akwado ngwakọta nke polypropylene (PP) na polyamide 6 (PA6) na carbon nanotubes multiwalled (MWNTs) site na iji usoro nhazi dị iche iche na ejima-screw micro-compounder.Achọpụtala mmetụta nke MWNT na omume crystallization nke usoro PP na akụkụ PA6 nke ngwakọta site na ọmụmụ ihe na-abụghị nke isothermal site na nyocha calorimetric dị iche iche.Ọzọkwa, mmetụta nke mgbakwunye nke compatibilizer (PP-g-MA) na mgbanwe nke MWNTs (m-MWNTs) na-abụghị covalent organic modifier (Li-nnu nke 6 amino hexanoic acid, Li-AHA) nwekwara. A mụrụ ya n'ihe gbasara omume crystallization nke PP na PA6 na ngwakọta.Ọmụmụ ihe ọmụmụ kristal egosila mmụba dị ukwuu na okpomoku kristal nke akụkụ PP na ngwakọta na ọnụnọ MWNT.Ọzọkwa, e guzobere usoro 'trans-lamellar crystalline' nke nwere PA6 'trans-crystalline lamellae' n'elu MWNTs n'ọnọdụ nke ngwakọta a kwadebere site na 'protocol 2' ma e jiri ya tụnyere ngwakọta kwekọrọ ekwekọ nke a kwadebere site na 'protocol 1'. .Nleba anya diffraction X-ray n'obosara egosila ịdị adị nke β-polymorph nke usoro PP n'ihi ntinye nke usoro PA6 na ngwakọta.Mgbakwunye nke MWNT na ngwakọta emewo ka ọ dịkwuo mfe nhazi nhazi β-crystalline nke usoro PP.N'ebe ndị m-MWNT nọ, a hụrụ β- ntakiri dị elu na oge PP ma e jiri ya tụnyere ngwakọta na MWNT pristine.Mgbakwunye PP-g-MA egbochila nhazi β-phase na usoro PP na ngwakọta.Nyocha ọtụtụ ederede X-ray kpughere na ntinye nke PA6 yana pristine/gbanwee MWNT emetụtala oke nghazi nke ụdọ PP n'akụkụ ụgbọ elu kristal dị iche iche na ngwakọta ngwakọta nke PP na PA6.
